Answer:
3.95m + 8.95b = 47.65
Step-by-step explanation:
m is the number of magazines, and b is the number of books. If it costs $3.95 for each magazine, you will get 3.95m. If it costs $8.95 for each book, you will get 8.95b. Both of these values add up to the total, which is $47.65.
5(2+x)=5
or, 10+5x=5
or, 5x= -5
or, x= -1
Hope it helps
y = 4x + 1
y = mx + b
b = y-intercept
From the graph we see that b = 1
m = slope
Start at (0, 1). Go up 8 units. Rise = 8. Go right 2 units. Run = 2.
slope = rise/run = 8/2 = 4
